In a 2-year field study conducted on a Gleyic Luvisol in Stuttgart-Hohenheim, root growth of one experimental and nine commercial maize cultivars was studied. According to the core method, roots of all cultivars penetrated the soil down to a depth of 150 cm indicating that no differences in...
Environmental stresses as major threats to global food security in the twenty-first century and improving biomass production and seed yield per area of crop plants become very critical. Plants are sessile organisms that cannot escape from environmental c
2018). The rth3 mutants used in these experiments are genetically highly homozygous because they have been backcrossed to the inbred line B73 for more than eight generations. The substrate loam was obtained by excavating 700 t of a haplic Phaeozem soil (from 0 to 50 cm depth) in Schla...
Sorghum plants have a fibrous root system, characteristic of grasses, which can reach a depth of up to 1.5–2.4 m (Kimber, 2000). An extensive root system and the ability to become dormant during water stress contribute to the drought resistance of sorghum, which makes it notable as an ...
Quantitative comparisons between both methods showed that minirhizotron observations resulted in (a) an underestimation of root density (RD) in the topsoil and (b) the description of a linear decline of RD with depth below 30 cm ... F Wiesler,WJ Horst - 《Zeitschrift Fuer Pflanzenernaehrung...
WT and tob1 display no observable difference in primary root length (E). Compared to Wt, tob1 displays increased total number of lateral roots (F), total lateral root volume (G), total lateral root length (H), and total lateral root depth (I) at certain time points. tob1 displays a...
After 5 yr coarse root mass to a depth of 85 cm was about 800, 1370, and 1530 gm in the succession, enriched succession and imitation of succession, respectively. At the final harvest, the 3.5yr-old C. alliodora plantation had 1000gm of coarse-root biomass. Roots < 1 mm in diameter ...
Root observations were conducted on vertical and superposed horizontal planes covered with a 2 cm grid short after silking. Root distributions expressed as index of density and/or dry mass density were estimated down to 1 m soil depth and with a distance to a plant base. For analysis of ...
The question in this context is therefore: What is the role of roots? With agrohydrologic models, the effect of root distribution on the course of actual transpiration in time can be evaluated. Take, for example, a grass vegetation (covering the soil completely), with a rooting depth of 80...
